Western Digital stock rocketed 52% over a six-day winning streak, closing at $746.23 as of June 18, 2026, driven by a wave of analyst price-target increases and soaring demand for hard disk drives from AI data centers.
On June 15, Morgan Stanley raised its price target on WDC to $650 from $488, maintaining an Overweight rating and citing strengthening demand for hard disk drives from AI data centers. JPMorgan lifted its target to $650 from $530 on the same day, pointing to stronger pricing power and expanding margins. Citi and Mizuho each moved targets to $685, while Bank of America and Wells Fargo raised targets to $610 and $575, respectively.
The rally reflects a structural shift in the storage market. Morgan Stanley estimated that HDD supply may run 10% to 15% short of demand in 2026, with AI-driven storage consumption growing at roughly 40% to 50% annually against supply growth of only 30% to 35%. Western Digital’s production capacity for 2026 is completely sold out, according to CEO Irving Tan, with the company holding long-term agreements with major AI infrastructure customers extending into 2027 and 2028.
The stock’s momentum builds on broader industry tailwinds. Western Digital has surged 282% since the start of 2026, according to Yahoo Finance reporting from June 17. The company showcased its Ultrastar Data 3000 JBOD platforms and higher-throughput hard disk drives at Computex 2026, positioning itself as storage infrastructure for AI workloads. In a separate move to strengthen its balance sheet, Western Digital swapped $858.4 million of 2028 convertible notes for cash and 21.3 million new shares, trimming near-term debt.
The recent surge extends a longer-term rally fueled by artificial intelligence adoption across the industry. AI companies have booked virtually all of Western Digital’s 2026 HDD production capacity, creating a supply-constrained environment that benefits pricing power. The company’s fiscal Q3 2026 revenue reached $3.34 billion, marking a 45.5% year-over-year increase, according to Investing.com, as hyperscalers prioritize securing storage for massive AI data lakes.
Analyst sentiment has shifted decisively. In February 2026, sentiment on WDC moved from Neutral in 2024 to Strong Buy across nearly all major firms, according to FinancialContent reporting. The stock’s volatile trading pattern—with 55 moves greater than 5% over the past year—reflects both the magnitude of the AI storage opportunity and the intensity of investor repositioning in the sector.
